PRO: Award-winning architect whose style has been praised for bridging the gap between architecture and engineering. He designed the new PATH train station at the World Trade Center site.

CON: His work is criticized as impracticalthe airport he designed in Bilbao, Spain, lacks proper facilities, and the bridge connecting to nearby hotels is prone to cracking and gets slippery when wet.
